The DBH 5144 oil seal is a single-lip radial shaft seal that mounts on rotating shafts to retain lubricant and block the entry of dust, water or particles. With dimensions of 45 mm shaft, 72 mm housing and 10 mm height, and Lz design, it is used in gearboxes, pumps, electric motors and transmission equipment. MR Accesorios Industriales carries it as an official brand and advises you on choosing the right oil seal for your application.

This item is a DBH 5144 radial shaft seal, identified by the designation 5144 and standardized dimensions: 45.00 mm shaft diameter, 72.00 mm housing diameter and 10.00 mm height. The Lz design corresponds to a single sealing lip with spring, intended for rotating shafts with lubrication. The lip elastomer runs against the shaft surface, while the outer diameter maintains the fit in the housing. It is a wear part that protects bearings, bushings and gears from contamination and oil loss.

Typical applications for an oil seal of these dimensions include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and chain or belt transmission equipment. It is also found in machine tools, conveyors and agricultural or road equipment where rotating shafts are exposed to dust and moisture. In all cases, its function is twofold: to retain the lubricant inside the assembly and to prevent external agents from entering the rolling or lubrication area.

To install a radial shaft seal, it is advisable to verify that the shaft has no burrs or deep marks in the contact area, and that the housing is clean and free of deformation. The lip is lubricated before inserting the part, and it is seated with a tube of suitable diameter so as not to damage the spring or the elastomer. Selection depends on shaft speed, operating temperature and the type of fluid to be retained. If the original oil seal has a different design or material, an equivalent alternative can be evaluated.

If you need an oil seal with nearby dimensions or an equivalent to the DBH 5144, the most practical approach is to send us the full code, the equipment brand and a photo of the old part. With that data we can compare shaft and housing diameters, height and lip type, and offer you an option that performs the same function. We can also check whether the Lz design is suitable for your speed and operating temperature.
